INDIANAPOLIS, Indiana (WXIN) – An Indianapolis man who pleaded guilty in a random killing spree was sentenced to three consecutive life sentences without parole, plus 16 years for armed robbery.

Johnathan Cruz admitted to be inspired by "The Purge" movie series during a four-day killing spree that resulted in the deaths of three people. Cruz chose his victims at random. In the movie series, people are given a day to commit any crime without prosecution.

Between May 12 and May 15 of 2016, Cruz killed Billy Boyd, Jay Higginbotham and Jose Alberto Ruiz. Prosecutors said he "killed for sport" and had planned to seek the death penalty in the case.

Darby says her family supports the plea deal which allowed Cruz to avoid the death penalty.

"When you have people paying debt to society, the death penalty is easy way out," said Darby.

While in court, Cruz offered no statement to the judge or families and showed no emotion. He did spew some profanity at our camera before the hearing.

"I was disappointed he didn't offer any sort of justification or apology to the family. I think it would have been meaningful to the families to hear that," said Curry.

Despite the lack of remorse, Boyd's sister says she prays every day that Cruz understands the pain his actions caused and her family has already forgiven him.

"It's hard. We'll never forget, but in order to move forward, we have to somehow forgive," said Darby.

According to court records, Cruz had help on the first two killings from Elijah Brooks who prosecutors have now charged with murder for supposedly driving the getaway car following two of the shootings.

A third suspect Steven Clark has also been charged with armed robbery in connection with one of the crimes.
